93 grand am... that's a Pontiac product. Burn it!
what is the car make and model? I have seen many questions on Olds Intrigue. 2002 Pontiac grand prix
Temp blend door actuator malfunction.
My mom had the same problem and we added freon and it blows very cold all over now.
vacuum line from intake manifold to control unit in dash broken or disconnected
blower motor resistor
the contour has problems with the blower motor switch and the resistor. I would check the resistor connector for signs of melting.
your fuse is blown. car manufacturerers make the dash lights go off when the tail light fuse blows so you know it is blown.
the heater blows warm air when fan is on low but blows cold air when fan is turn to higher setting
sounds like your water pump ain't pumping, don't drive it till it is!. could be as simple as a new fan bewlt or might even need a pump
heater core could be plugged, also check for low coolant
check you thermostat for the temp setting
